lNCANDES CENT-LAMP STAND AND REFLECTOR.

SPECIFICATION forming part of Letters Patent No. 525,909, datedSeptember 11, 1894.

Application filed June 9, 1894- I To all whom it may concern:

Be it known that I, GEORGE KLEMM, a citizen of the United States,residing at the city of Philadelphia, in the county of Philadelphia andState of Pennsylvania, have invented certain new and useful Improvementsin Lamp Stands and Reflectors, of which the following is aspecification.

My invention has relation to a portable and adjustable appliance 'forapplication to an article of furniture provided with an electric lampmounted in a slotted reflecting tube or cylinder and arranged in suchmanner that illumination derived from the lamp is conoentrated in anyrequired direction; and in such connection my invention relates to theparticular construction and arrangement of such an appliance adapted forsaid purpose.

My invention consists of an appliance for reflecting and concentratingthe illumination derived from an electric lamp, constructed and arrangedin the manner hereinafter described and claimed.

The nature and characteristic features of my invention will be morefully understood from the following description taken in connection withthe accompanying drawings, forming part hereof, and in which- Figure 1,is a perspective view of an appliance embodying features of my inventionprovided with an arched standard secured to a rectangular base andhaving a perforated and slotted reflecting tube or cylinder connect'edby means of a knuckle-joint connection with said'standard and providedwith a tightening device and also showing an incandescent electric lampdisposed lengthwise in said tube or cylinder. Fig. 2, is a similar viewof a modified form of an appliance embodying features of my invention,showing the leading in wires from a source of energy connected therewithand also showing the means for securing the diflerent adjustments of theappliance from the holder thereof; and Fig. 3, is a vertical centralsection through the extensible arm of Fig. 2 adapted to be detachablyclamped to a base and showing the manner of introducing the leading inWires therethrough to an electric lamp adapted to be rigidly secured tothe reflecting corrugated slotted tube or cylinder provided with orna-Serial No. 514,037. (No model.)

.mental conical shaped ends, as illustrated in Fig. 2.

Referring to the drawings A, is a rectangular base provided with acone-shaped cap a, into which is secured a standard at, having the upperportion arched with the forward extremity thereof provided with abifurcated bearing of, with which engages the tongue of, of a hanger asecured to a reflecting device E, and which tongue engagingsaidbifurcated bearing of, constitutes a knuckle-joint connection B. Thisconnection B, is provided with a set screw a whereby said reflectingdevice may be adjusted in two difierent directions, that is to say,either upward or downward in an are or substantially so of a circle, aswill be readily understood from Figs. 1 and 2. The reflector E, has aportion thereof cut away so as to form an oblong slit 6, as clearlyshown in Fig. Land with perforations e, in the surface thereof, forventilating the same. This device may be made of corrugated or plainmetal and the interior may be either highly polished or coated with amaterial or substance which is adapted to insure proper reflection beingderived therefrom, when an illuminating body such as an electric lamp F,is placed lengthwise therein and so as to be held rigidly by the socketf, thereof from one of the ends of the same. This device E, is providedwith cone-shaped ends e and o either plain or ornamented, as shown inFigs. 1 and 2, and through one of which ends is inserted and detachablysecured a rubber plug or the like 0 for a purpose to be presentlyexplained. From said socket f, the leading in wires 1 and 2, areconnected therewith and extend through the insulating plugs 0 and 0seated in one end of said reflector E, and also in the supporting arm orstandard a, of the device and leading to a source of energy, not shown,whereby when the current is established through the lamp from saidsource of energy said reflecting device by means of said knuckle-jointconnection B, may be caused to assume the required position to reflectand concentrate the illumination derived from said lamp in requireddirections; and moreover, to thoroughly screen the eyes from the sourceof direct illumination derived from said appliance.

The appliance of Fig. 2, is the same as that of Fig. 1, with theexception that in this instance a horizontal arm is connected by meansof a clamp 0 with a rectangular base 5 A, and said clamp being providedwith a set screw 0 the opposite end of said arm a, being provided with aknuckle-joint connection B, having a set-screw a with which connectionis attached a hanger a secured to the re- 10 fiector E, made in thisinstance of corrugated metal and having truncated cone-shaped orornamental ends e and e. The leading in wires 1 and 2 pass through thehorizontal arm 0 and downward through an opening provided in the forwardportion thereof through an inserted rubber bushing or plug 0 and througha like bushing or plug 0 inserted into one of the truncated cone-shapedends e or e, of the slotted reflector E, to the socket of anincandescent electric lamp to be disposed lengthwise therein and securedto said device in such manner as to permit of the turning of the samewith the reflector E, in order to cause the latter to assume the re- 2 5quired position, for concentrating the illumination derived from saidlamp and so as not to become a strain upon the eyes in the deflectionthereof. It will be observed by reference to Fig. 1, that the reflectingdevice is susceptible of a half-rotary movement to and 0 from the archedportion of the standard a, through the knuckle-joint connection B,thereof and in Fig. 2, that the device is susceptible of a back andforth movement, as well as a reciprocating or rotary movement by meansof the connections hereinbefore explained in the description of thedevice of Fig. 2, of my invention.

Having thus described the nature and objects of my invention, what Iclaim as new, and desire to secure by Letters Patent, is-

The combination of a base, a supporting arm connected with said base soas to secure reciprocatory motion, a slotted tube, a hanger attached tothe middle thereof, and a knuckle- 5 joint connection between saidsupporting arm and hanger, substantially as and for the purposes setforth.

In testimony whereof I have hereunto set my signature in the presence oftwo subscrib- 5o ing witnesses.

GEORGE F. KLEMM.
